SSLCTXaddsession(3) OpenSSL SSLCTXaddsession(3)

NAME
       SSLCTXaddsession, SSLaddsession, SSLCTXremovesession,
       SSLremovesession - manipulate session cache

SYNOPSIS
        #include 

        int SSLCTXaddsession(SSLCTX *ctx, SSLSESSION *c);
        int SSLaddsession(SSLCTX *ctx, SSLSESSION *c);

        int SSLCTXremovesession(SSLCTX *ctx, SSLSESSION *c);
        int SSLremovesession(SSLCTX *ctx, SSLSESSION *c);

DESCRIPTION
       SSLCTXaddsession() adds the session cc to the context ccttxx. The
       reference count for session cc is incremented by 1. If a session with
       the same session id already exists, the old session is removed by
       calling SSLSESSIONfree(3).

       SSLCTXremovesession() removes the session cc from the context ccttxx.
       SSLSESSIONfree(3) is called once for cc.

       SSLaddsession() and SSLremovesession() are synonyms for their
       SSLCTX*() counterparts.

NNOOTTEESS
       When adding a new session to the internal session cache, it is examined
       whether a session with the same session id already exists. In this case
       it is assumed that both sessions are identical. If the same session is
       stored in a different SSLSESSION object, The old session is removed
       and replaced by the new session. If the session is actually identical
       (the SSLSESSION object is identical), SSLCTXaddsession() is a no-
       op, and the return value is 0.

       If a server SSLCTX is configured with the
       SSLSESSCACHENOINTERNALSTORE flag then the internal cache will not
       be populated automatically by new sessions negotiated by the SSL/TLS
       implementation, even though the internal cache will be searched
       automatically for session-resume requests (the latter can be surpressed
       by SSLSESSCACHENOINTERNALLOOKUP). So the application can use
       SSLCTXaddsession() directly to have full control over the sessions
       that can be resumed if desired.

RETURN VALUES
       The following values are returned by all functions:

       0
            The operation failed. In case of the add operation, it was tried to add
            the same (identical) session twice. In case of the remove operation, the
            session was not found in the cache.

       1
            The operation succeeded.
